# Preload missing valid ‘as’ value

 * Hi Frank,
 * I’m trying to use the new preload feature available under Extra Settings.
    However
   when specifying a URL for preloading it doesn’t work (no preloading) and Chrome
   developer tool is throwing the following console message: “<link rel=preload>
   must have a valid `as` value”. Digging deeper into the code the AO plugin seems
   to add the following and ‘other’ doesn’t seem to be a valid value: <link rel=”
   preload” href=”[https://www.art-maupin.de/wp-content/plugins/revslider/public/assets/fonts/revicons/revicons.woff?5510888&#8243](https://www.art-maupin.de/wp-content/plugins/revslider/public/assets/fonts/revicons/revicons.woff?5510888&#8243);
   as=”other”>
 * I guess as=font would be appropriate in my case according to [https://www.w3.org/TR/preload/#as-attribute](https://www.w3.org/TR/preload/#as-attribute)
   but there is no option in the AO plugin settings to specify the AS-type.
 * Am I overseeing something here or does the plugin require an enhancement to allow
   specification of the AS-type for any preload URLs ?
 * Thanks a lot
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fpreload-missing-valid-as-value%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Remove `?5510888″` from the URL so it becomes `https://www.art-maupin.de/wp-content/
   plugins/revslider/public/assets/fonts/revicons/revicons.woff` and it should work
   🙂
